Outline of Final Research Achievements |
The principal investigator has proposed and been working on highly functional mode-locked fiber lasers, such as short-pulse fiber lasers using carbon nanotube (CNT) or graphene, and dispersion-tuned wavelength swept lasers. This study aims at the new developments of these highly functional mode-locked fiber lasers towards mid-infrared (MIR) wavelength regions, and new applications to medical and industrial sensings, such as spectroscopy, optical coherence tomography (OCT), and Lidar. We have succeeded in generating MIR short pulse and broadband SC comb, and applied it to the spectroscopy. We also proposed novel mode locking method. We applied the dispersion-tuned lasers to spectroscopy and OCT, and also showed the performance improvement of OCT and Lidar with the aid of digital signal processing.
